Cleanliness, efficiency, compactness, cool-factor... for a variety of reasons, automatic doors have become a standard feature of Japanese shops. While the typical sliding star-trek style design has proven itself, the tanaka auto door aims to improve upon a good concept. This new design entails strips equipped with infrared sensors that open to the approximate shape of the person or object passing through, minimizing entry of dust, pollen, and bugs while keeping precious air-conditioning in. The technology for the new design seems to be in it's infancy, but Japan has proven once again that it's a least 10 years ahead of everyone else. -JM
